The silicone oils with radiation resistance are mainly phenyl silicone oils.
Phenyl silicone oil is the product of partial methyl substitution of phenyl in methyl silicone oil. Its radiation resistance mainly comes from the strong bond energy of silicon-oxygen bonds, which can resist the damage of radiation. At the same time, the conjugated system of benzene ring can absorb radiation energy and reduce the damage of radiation to silicone oil.
Phenyl silicone oil can withstand high-dose radiation exposure, and is not easy to oxidize in a radiation environment, and can maintain stability. It also has good high and low temperature performance, which can maintain fluidity at low temperatures and can be used stably in a higher temperature environment.
Due to its excellent radiation resistance, phenyl silicone oil can be used in high radiation environments such as nuclear energy, aerospace, and medical treatment. It can be used as a high and low temperature lubricant for electronic and electrical equipment, and can also be used as a heat treatment bath for metal products, high temperature heating oil, etc. In addition, polymethylphenylsiloxane terminated with methyldiphenylsiloxy, that is, phenylmethyl silicone oil, also has excellent radiation resistance, and also has high temperature performance, lubricity and low freezing point.
